Mouse device

A mouse device, comprising:

• a battery module including a first connection interface and a display interface;
• a casing including a second connection interface and a third connection interface;
• and
• a control circuit disposed inside the casing and electrically connected to the second connection interface and the third connection interface;
• wherein the battery module is detachably mated with the second connection interface through the first connection interface, and the battery module is exposed outside of the casing when being mated with the second connection interface;
• wherein the third connection interface is used for connecting a transmission line;
• wherein the control circuit controls an operation of the mouse device to be in a wired mode or a wireless mode according to a connection status of the second connection interface and the third connection interface;
• wherein the third connection interface includes a third electrically conducting interface and a first thread part, and the transmission line includes a fourth electrically conducting interface and a second thread part;
• wherein, when the transmission line is engaged with the third connection interface, the first thread part is threadedly engaged with the second thread part, so that the third electrically conducting interface is connected to the fourth electrically conducting interface;
• wherein, when the first connection interface of the battery module is mated with the second connection interface of the casing, the control circuit transmits an operating status of the mouse device to the display interface through the second connection interface being connected to the first connection interface, the operating status includes setting information of a macro command, a dots per inch of the mouse device or a polling rate of the mouse device.
